Refund & Return Policy

Effective Date: August 9, 2026

At Corelyn (operated as Zinchenko Daniil Onlinehandel), customer satisfaction is our top priority. We stand behind the quality of our products and want you to feel completely confident in your purchase. That is why we offer a 30-Day Risk-Free Money-Back Guarantee from the date your order is delivered.

1. 30-Day Money-Back Guarantee You may request a return and full refund within 30 days from the date your order is delivered. To be eligible for a return under our 30-day guarantee: • The product must be returned in good, working condition with all original components, cables, and accessories included. • The product must not have been intentionally damaged, modified, or misused. • Opened packaging and standard testing of the product at home are fully acceptable.

2. How to Request a Return To initiate a return, please contact our customer support team within 30 days of receiving your order at: Email: support.kneerelief@gmail.com

Please include the following details in your message: • Your full name • Your order number • Reason for the return • Photos or a short video of the item (if reporting damage or a defect)

Our support team will respond within 24–48 hours to approve your request and provide detailed return instructions, including the correct designated return address. Please do not send items back without contacting us first.

3. Return Shipping Costs • Customer Volitional Returns: For standard voluntary returns under our 30-day guarantee (e.g., change of mind, personal preference), the customer is responsible for the return shipping costs and obtaining a valid tracking number. • Damaged, Defective, or Incorrect Items: If your order arrives damaged, defective, or incorrect, please notify us immediately. Corelyn will cover 100% of the return shipping costs or issue an immediate replacement at no extra charge.

4. Refunds & Processing Time • Once your returned package is received and inspected at our fulfillment center, we will notify you via email regarding the approval of your refund. • Upon approval, your full refund will be processed automatically back to your original payment method (Credit Card, PayPal, etc.). • Refunds are typically processed within 3 to 5 business days after receiving the return. Depending on your financial institution, it may take an additional 2–5 business days for the funds to reflect in your account.

5. Exchanges & Replacements If you receive a defective or damaged unit, we will gladly ship you a brand-new replacement product free of charge. If you need an exchange for any other reason, please contact our support team to discuss available options.

6. Exceptions & Non-Returnable Items We reserve the right to decline a return or refund request if: • The return request is submitted after the 30-day delivery window has expired. • The product shows signs of intentional physical abuse, severe unauthorized modification, or damage caused by improper usage outside normal operation.
